Description

camera device

This embodiment relates to a camera device.

As various types of mobile terminals become more widespread and wireless Internet services become commercialized, consumer demands related to mobile terminals are diversifying, and various types of additional devices are being installed in mobile terminals.

A prime example is a camera device that captures images or videos of a subject. Meanwhile, recent camera devices incorporate image stabilization features to prevent image blur caused by the photographer's hand movements.

One method of performing image stabilization is the module tilt method. In conventional module tilt camera devices, the electrical signals from approximately 20 or more image sensors are connected to a fixed part via a printed circuit board (PCB) to allow movement of the image sensors.

However, this approach poses a problem: restrictions on the movement of the movable part occur, and significant resistance (load) to the movement of the movable part also acts. Furthermore, the dispersion of the elastic modulus due to the dispersion of the Young's modulus of the PCB's internal raw materials and PCB processing tolerances significantly increases the dispersion of the elastic modulus, requiring additional work to reduce this performance dispersion.

In particular, since the PCB structure has high radial rigidity, it has high resistance to rotational drive, and thus the mentioned structure has a problem in that it is difficult to apply it for compensation in the rolling direction, that is, compensation for rotational shaking.

The coil (220) may be coupled to the inner surface of the third substrate (230). The coil (220) may be electrically connected to the third substrate (230). When current is applied to the coil (220), an electric field may be formed around the coil (220). When current is applied to the coil (220), an electromagnetic interaction between the coil (220) and the magnet (320) may cause one of the coil (220) and the magnet (320) to move relative to the other. In the present embodiment, when current is applied to the coil (220), the magnet (320) may move. However, in a modified example, the positions of the coil (220) and the magnet (320) may be arranged opposite to each other.

The coil (220) may include a first coil (221). The first coil (221) may face the first magnet (321). The first coil (221) may be electrically separated from the second coil (222) and the third coil (223). The first coil (221) may receive current separately from the second coil (222) and the third coil (223). The first coil (221) may be controlled separately from the second coil (222) and the third coil (223). When current is applied to the first coil (221), current may not be applied to the second coil (222) and the third coil (223). In addition, when current is applied to the first coil (221), current may be applied to the second coil (222) and the third coil (223). When current is not applied to the first coil (221), current may be applied to the second coil (222) and the third coil (223). Of course, current may not be applied to all of the first to third coils (221, 222, 223). That is, the first to third coils (221, 222, 223) may be individually controlled. The first to third coils (221, 222, 223) may be independently controlled. In other words, the direction and amount of current applied to each of the first to third coils (221, 222, 223) may be individually controlled. The first coil (221) can rotate the camera module (600) around a first axis perpendicular to the optical axis through interaction with the magnet (320). The first coil (221) can tilt the camera module (600) around a first axis perpendicular to the optical axis through interaction with the magnet (320). The camera module (600) can be pivotally driven around a first axis perpendicular to the optical axis. In this case, the first axis may be the x-axis.

As illustrated in (b) of Fig. 17, the first coil (221) can rotate the camera module (600) to one side about the x-axis (see b of (b) of Fig. 17) through interaction with the magnet (320). More specifically, when a positive current is applied to the 1-1 coil (221-1), an upward electromagnetic interaction force (b1) is generated between the 1-1 coil (221-1) and the 1-1 magnet (321-1), and when a positive current is applied to the 1-2 coil (221-2), a downward electromagnetic interaction force (b2) is generated between the 1-2 coil (221-2) and the 1-2 magnet (321-2), so that the camera module (600) can rotate to one side about the x-axis (b). However, it is not limited to the currents in the same direction being applied to the 1-1 coil (221-1) and the 1-2 coil (221-2), and as a variation, currents in different directions may be applied. In addition, currents in opposite directions may be applied to the 1-1 coil (221-1) and the 1-2 coil (221-2).

As illustrated in (b) of Fig. 18, the first coil (221) can rotate the camera module (600) to the other side about the x-axis (see e of (b) of Fig. 18) through interaction with the magnet (320). More specifically, when a reverse current is applied to the 1-1 coil (221-1), a downward electromagnetic interaction force (e1) is generated between the 1-1 coil (221-1) and the 1-1 magnet (321-1), and when an upward current is applied to the 1-2 coil (221-2), an upward electromagnetic interaction force (e2) is generated between the 1-2 coil (221-2) and the 1-2 magnet (321-2), so that the camera module (600) can rotate to the other side about the x-axis (e).

The first coil (221) may include a plurality of coils. The first coil (221) may include a 1-1 coil (221-1) and a 1-2 coil (221-2). The 1-1 coil (221-1) may face the 1-1 magnet (321-1). The 1-2 coil (221-2) may face the 1-2 magnet (321-2). The 1-1 coil (221-1) may be arranged between the 2-1 coil (222-1) and the 2-2 coil (222-2). The 1-2 coil (221-2) may be arranged between the 2-3 coil (222-3) and the 2-4 coil (222-4). The first-first coil (221-1) and the first-second coil (221-2) can be electrically connected. Through this, the first-first coil (221-1) and the first-second coil (221-2) can be controlled integrally. However, as another example, the first-first coil (221-1) and the first-second coil (221-2) can be electrically separated. The first-first coil (221-1) and the first-second coil (221-2) can individually receive current. In this case, the first-first coil (221-1) and the first-second coil (221-2) can be individually controlled. That is, the direction and amount of current applied to each of the first-first coil (221-1) and the first-second coil (221-2) can be individually controlled.

The coil (220) may include a second coil (222). The second coil (222) may face the first magnet (321). The second coil (222) may be electrically isolated from the first coil (221). The second coil (222) and the first coil (221) may be individually energized. The second coil (222) and the first coil (221) may be individually controlled. The second coil (222) may rotate the camera module (600) about a second axis perpendicular to the optical axis and the first axis through interaction with the magnet (320). The second coil (222) may tilt the camera module (600) about a second axis perpendicular to the optical axis and the first axis through interaction with the magnet (320). The camera module (600) can pivot around a second axis perpendicular to the optical axis and the first axis. In this case, the second axis may be the y-axis.

As shown in (a) of Fig. 17, the second coil (222) can rotate the camera module (600) to one side around the y-axis (see (a) of Fig. 17) through interaction with the magnet (320). In more detail, when a forward current is applied to the 2-1 coil (222-1), an upward electromagnetic interaction force (a1) is generated between the 2-1 coil (222-1) and the 1-1 magnet (321-1), and when a forward current is applied to the 2-3 coil (222-3), an upward electromagnetic interaction force (a1) is generated between the 2-3 coil (222-3) and the 1-2 magnet (321-2), and when a reverse current is applied to the 2-2 coil (222-2), a downward electromagnetic interaction force (a2) is generated between the 2-2 coil (222-2) and the 1-1 magnet (321-1), and when a reverse current is applied to the 2-4 coil (222-4), a downward electromagnetic interaction force (a2) is generated between the 2-4 coil (222-4) and An electromagnetic interaction force (a2) is generated downward between the first and second magnets (321-2), so that the camera module (600) can rotate (a) to one side around the y-axis. The electromagnetic interaction force (a1) between the 2-1st coil (222-1) and the 1-1st magnet (321-1) and the electromagnetic interaction force (a1) between the 2-3rd coil (222-3) and the 1-2nd magnet (321-2) are directed in the same direction, the electromagnetic interaction force (a2) between the 2-2nd coil (222-2) and the 1-1st magnet (321-1) and the electromagnetic interaction force (a2) between the 2-4th coil (222-4) and the 1-2nd magnet (321-2) are directed in the same direction, but the electromagnetic interaction force (a1) between the 2-1st coil (222-1) and the 1-1st magnet (321-1) and the electromagnetic interaction force (a1) between the 2-2nd coil (222-2) and the 1-1st magnet (321-1) are directed in the same direction. The interaction force (a2) may be directed in different directions. For example, the electromagnetic interaction force (a1) between the 2nd-1st coil (222-1) and the 1st-1st magnet (321-1) and the electromagnetic interaction force (a1) between the 2nd-3rd coil (222-3) and the 1st-2nd magnet (321-2) may be directed upward, and the electromagnetic interaction force (a2) between the 2nd-2nd coil (222-2) and the 1st-1st magnet (321-1) and the electromagnetic interaction force (a2) between the 2nd-4th coil (222-4) and the 1st-2nd magnet (321-2) may be directed downward. It is described that currents in different directions are applied to the 2-1 coil (222-1) and the 2-2 coil (222-2), but as a variation, the winding directions of the coils may be arranged in opposite directions and currents in the same direction may be applied.

As shown in (a) of Fig. 17, the second coil (222) can rotate the camera module (600) to the other side around the y-axis (see d of (a) of Fig. 17) through interaction with the magnet (320). In more detail, when a reverse current is applied to the 2-1 coil (222-1), a downward electromagnetic interaction force (d1) is generated between the 2-1 coil (222-1) and the 1-1 magnet (321-1), and when a reverse current is applied to the 2-3 coil (222-3), a downward electromagnetic interaction force (d1) is generated between the 2-3 coil (222-3) and the 1-2 magnet (321-2), and when a forward current is applied to the 2-2 coil (222-2), an upward electromagnetic interaction force (d2) is generated between the 2-2 coil (222-2) and the 1-1 magnet (321-1), and when a forward current is applied to the 2-4 coil (222-4), a downward electromagnetic interaction force (d2) is generated between the 2-4 coil (222-4) and An upward electromagnetic interaction force (d2) is generated between the first and second magnets (321-2), so that the camera module (600) can rotate (d) to the other side around the y-axis.

The second coil (222) may include a plurality of coils. The second coil (222) may include 2-1 to 2-4 coils (222-1, 222-2, 222-3, 222-4). The 2-1 coil (222-1) may face the 1-1 magnet (321-1).

The second-fourth coil (222-4) may be arranged on the other side of the first-second coil (221-2).

The 2nd to 2nd-4th coils (222-1, 222-2, 222-3, 222-4) can be electrically connected. Through this, the 2nd to 2nd-4th coils (222-1, 222-2, 222-3, 222-4) can be controlled integrally. However, as another example, the 2nd to 2nd-4th coils (222-1, 222-2, 222-3, 222-4) can all be electrically separated. In this case, the 2nd to 2nd-4th coils (222-1, 222-2, 222-3, 222-4) can be individually controlled. That is, the direction and amount of current applied to each of the 2-1 to 2-4 coils (222-1, 222-2, 222-3, 222-4) can be individually controlled. As another example, the 2-1 coil (222-1) and the 2-3 coil (222-3) can be electrically connected, the 2-2 coil (222-2) and the 2-4 coil (222-4) can be electrically connected, and the 2-1 coil (222-1) and the 2-2 coil (222-2) can be electrically separated.

At this time, the first direction and the second direction are each a tangential direction of a circle centered on the optical axis and may be symmetrical with respect to the optical axis. Although it has been described that a positive current is applied to each of the 3-1 coil (223-1) and the 3-2 coil (223-2), as a modification, currents in different directions may be applied to the 3-1 coil (223-1) and the 3-2 coil (223-2). At this time, the required electromagnetic interaction force may be induced through the arrangement direction of the 2-1 magnet (322-1) and the 2-2 magnet (322-2) or the winding direction of the 3-1 coil (223-1) and the 3-2 coil (223-2).

At this time, the third direction and the fourth direction are each a tangential direction of a circle centered on the optical axis and may be symmetrical with respect to the optical axis. In addition, the third direction may be the opposite direction of the first direction and the fourth direction may be the opposite direction of the second direction.

Through this, the third-first coil (223-1) and the third-second coil (223-2) may be controlled integrally. However, as another example, the third-first coil (223-1) and the third-second coil (223-2) may be electrically separated. In this case, the 3-1 coil (223-1) and the 3-2 coil (223-2) can be individually controlled. That is, the direction and amount of current applied to each of the 3-1 coil (223-1) and the 3-2 coil (223-2) can be individually controlled.

However, as a modification, the first magnet (321) may be a bipolar magnet having two single magnets each having two poles overlapping each other. The upper portion of the first magnet (321) may be a north pole and the lower portion may be a south pole.

In the present embodiment, the upper elastic member (410) is offset bent, and a preload is applied in the product assembly state. In the present embodiment, even if a change in the direction of gravity occurs, the preload, which is a vertical force, is sufficiently large compared to the weight of the camera module (600), so that sagging of the camera module (600) due to the difference in attitude may not occur. Referring to FIG. 15, an offset banding structure that generates a height difference (see a of FIG. 15) between the first connecting portion (411) and the second connecting portion (412) of the upper elastic member (410) can be confirmed.
